Coupling between dielectric waveguide mode and long range surface plasmon polariton waveguide mode

Abstract

Coupling between long range surface plasmon polariton (LRSPP) waveguide mode and dielectric waveguide (DW) mode has been studied theoretically and experimentally. It is demonstrated that the fundamental and second-order TM-polarized mode of dielectric waveguide could couple with LRSPP mode efficiently, respectively.
